An XLSB file is a spreadsheet workbook created by Microsoft Excel, a program used to create and edit spreadsheets. It contains one or more spreadsheets with cells arranged by a grid of rows and columns, as well as charts, macros, and formatting. XLSB files are saved in a binary format.

You can open XLSB files with Microsoft Excel in Windows and macOS. You can also open XLSB files with OpenOffice Calc (multiplatform).

However, Excel is the best option for opening XLSB files because it fully supports the formatting of Excel spreadsheets, which may include graphs and the spacing of data fields. To open an XLSB file with Excel, select File → Open → Browse, then choose the XLSB file you would like to open.
